Distorted sound when using audio cable splitter.

I have a JBL creatures speaker system, which has a 3.5mm input at the back which I use to connect a lead to my tv, via the 3.5 mm headphone socket so it plays through my speakers. Now I have just purchased an Amazon Dot, which I also want to output to my speakers, so instead of having to keep disconnecting the lead from the tv to plug into the Dot, I purchased a stereo audio splitter to plug into the back of the Creature’s woofer, so I could connect both the tv and Dot to the woofer. The sound from the Dot is great, but the sound from the TV is very dull, I have to turn it up quite loud, and even then it doesn’t sound right.
Can anyone give me advice as to why the tv’s audio is like this?
Many Thanks.

I assume you haven't tried another splitter? That could be the problem.

When you say stereo audio splitter, are the 2 jacks which plug into the TV and Dot actually stereo?



Does unplugging the jack from the Dot make a difference?


EDIT: actually just found this which probably explains it - http://www.tomshardware.co.uk/answer...lume-loss.html

Thanks for your advice KeyserSoze, I’ll definately look into what you suggest. I also posted on another forum, and someone thinks that the two inputs are clashing electrically. The splitter is working as a combiner, which is not what I need.
What I do need, he suggests is a 2xinput and 1xoutput switch like the following.

What you're doing is connecting the two output drivers together in parallel. As they are both trying to drive the cable you have contention which is why you have sound problems (the tv is trying to drive a signal while the dot is simultaneously trying to drive the cable low).

As you say you need something that will actually switch the signal.
